crowded tables

My question is on the negative aspect of a crowded table (5, 6 or 7 players at once) when the count is high. I understand that if there are a lot of players; the good sections of the deck will end faster. But since I play only 6 deck shoes (the only game available where I live ) the good portion tends to last a little longer.

So my question: Without talking about the rapid depletion of cards by having a lot of players in the table. What other disadvantages or (advantages) are there if you play a crowded tables ?

Thank you
